From that day, Gin has to go to the boiled water and sat there till he can't handle it anymore. Although it is little, his skin has become harder and his regeneration is also healed him faster.
Today, he is currently sitting in the tub till he can't anymore but
"Gin, get out of the tub and wait for a while," said Old 1 who is supervising the training.
Gin also got out of the tub without telling anything but he knows what is going to happen.
Old 1 gestured to the disciple who are carrying the ground pots and they stood beside the tub while waiting for the water in the tub to be put out by the other disciples.
After all the water in the tub is put out, the disciples who are carrying the ground pots poured the silvery liquid into the tub.
Gin looked at the liquid and said to Old 1 "Old 1, is it mercury you are pouring?"
"Yes, Gin. You have a pair of good eyes for a black heart. This time you will have to hold your breath as the inhalation of mercury is not good for the inner parts of the body. Although you have a good regeneration ability, we don't know that it is effective in the inner parts of the body. Now hop in," said Old 1.
Gin looked at the mercury in the tub and dipped it slowly. From the start, he didn't feel anything but little by little he began to feel the heat and the mercury getting into his body through the pores of his body.
While Gin is 'training' his best, Saitama is currently facing one of the hardest challenges of his life. That is the written test of the hero association.
"Why do you want to be a hero?
If an old man and a small child are in danger at the same time who would you choose to save?
The monster is holding the hostage of a boy and how will you save the boy without him getting injured?
Etc, etc."
Saitama read the test and thought for quite a long time but the only thing that appeared in his mind about the answers is 'Kill the monsters immediately" so he answered all the questions with that same answers.
After written tests, Saitama is brought to the area where their physical strength will be tested.
On the higher floor that can watch the physical that is happening on the ground floor, there are five executives that are standing and watching the test that is carried out.
"Who is the guy that Dark lancer is recommended?" said Hwari.
"Tsk, that guy with the nearly bald head," said Kirisa.
McCoy looked at the exchange between Hwari and Kirisa. He thought how childish for them to fight because of a single hero. Although he is thinking like that he is searching for a way to make Dark lancer contract him with the confidential advisor but Hwari got the contract quickly before he managed to prepare.
Agoni is looking at the people who came to take the test and he hoped that more people will become qualified heroes as the last attack all over the cities really made the number of heroes in the lower brackets like B and C reduced.
Agoni is also looking at Saitama who is taking the sprint exam and he saw that Saitama ran at a breathtaking speed as the contenders in his bracket can't even see his shadow. Not only Sprint, but Saitama also aced all the physical tests and he went to the resting area.
The performance of Saitama is seen by all the executives on the floor and they agreed to put him in B rank.
From this test, they saw a few marital artists who came to participate and the executives can see that they are also quite strong so they agree to let them start from B rank.
Although people like Saitama and martial artists are fewer and more than 20 people are qualified for C rank although the number of people who participated in the exam is more than 400.
From the mic, a woman is telling the people who failed to be a hero to go into the waiting area as the training tips to increase their strength will be told by their hero association trainers.
The reason the hero association told the people who failed to wait for them to get the training of the trainers as they want to produce more heroes and to produce more heroes they will have to make the C-rank hero survive the monster attacks.
The main reason the C-rank heroes lead to death is that they don't know how to estimate the strength of the monsters and that lead to them going into the other lives quickly.
This idea is proposed by Guiches who propose because he thought that the more heroes there is the bigger the talent pool for the people with superior talent to surpass the other heroes while stepping on their back.
In the locker room, Saitama is changing his clothes while thinking about what to eat for dinner. What he didn't notice is that beside him 3 martial artists, 2 swordsmen, and some men with bulging muscles who are flexing without even trying that much.
That locker room is the people who are qualified for B rank from the start of their hero carrier. Every person in the room except for Saitama is thinking about how the hell this short and nearly bald man managed to start from B rank as from their perceptions they don't feel any kind of pressure or danger from Saitama.
As they are waiting room, the door is opened and the staff told them that they will have to listen to the words of the executive of the hero association before they get their hero license.
They are brought to another room and they saw a man with the afro head waiting there standing on the podium while gazing at every single one of them like he wanted to see through their skins.
"Welcome to the hero association my name is Lazina who is currently working as one of the executives of the hero association. I would like to start with names and how you want to be a hero?" said Lazina
